function varargout = Winkler1(varargin)
% Winkler1 MATLAB code for Winkler1.fig
%      Winkler1 by itself, creates a new Winkler1 or raises the
%      existing singleton*.
%
%      H = Winkler1 returns the handle to a new Winkler1 or the handle to
%      the existing singleton*.
%
%      Winkler1('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in Winkler1.M with the given input arguments.
%
%      Winkler1('Property','Value',...) creates a new Winkler1 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Winkler1_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Winkler1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
